Python Calculator

A calculator made in python.

This application uses the Reverse Polish Notation for calculations.

The algorithm is written in C++, but the user interface is made in PySimpleGui.

• You can check out the issues or the to-do list at the bottom of this readme.

How to build

1. Just building the python code

• Install python
• Install PySimpleGUI pip install PySimpleGUI
• Install playsound pip install playsound
• Make sure that the .pyd file and the .py file are in the same folder
• Just do this line in the same directory as the files. python CalculatorUI.py
• It should work.

2. Building the c++ code and using pybind11

CMake

• Make sure you have cmake and pybind11 installed.
• Go to the c++ folder. In the project directory do: cd src/c++
• Sometimes CMake can have problems with finding pybind11. To fix this try this:
  • In console pip show pybind11.
  • In CMakeLists.txt change [LOCATION] to the location you get from the command.
  • If your path contains single escape characters \ make sure to replace them with \\
  • cmake .
  • cmake --build .
  • The .pyd file should be located in one of the folders created.
  • Now you can move the .pyd file to the python src folder and build the rest.

Visual Studio

• This process is quite complicated and I myself had a lot of problems with using pybind.
• I'm going to leave this guide. It does a much better job explaining this than I could.

To do list

• Write the rpn algorithm in C++ [x]
• Write tests to make sure things are running smoothly [x]
• Organize rpn code to be more readable [x]
• Bind the C++ code to python [x]
• Create a GUI [x]
• Add functionality to the GUI [x]
• Fix all the bugs [ ]
• Add documentation [ ]
• Light and dark mode [ ]
• Window confirming if the user wants to exit the calculator [x]
